Next, pick your place to farm. Hydra farming around Augury Rock, green item drops at Sorrow's Furnace, raptor farming in EOTN, it's wide open. Ask around in towns for good farming areas and get in with an experienced farming party for best results.

I suggest following the main quest line to level up naturally, taking a few side quests along the way. This will also open up new areas you can come back to and farm later when you reach the level cap of 20.

You could also hire a power leveler in one of the towns who will take you out and kill powerful enemies while you stand by and gain the experience. Of course, expect to pay for the service. Rates vary with the person doing the deed.
